JOSEPH J. HASKIN, OF TUCSON, ARIZONA.

OIL-BURNER.

To all whom it may concern: i

Be it known that I, JOSEPH J.'HA'sK1N, citizen of the United States, residin' at Tucson, in the county 'of- Pima a'hdy tate of Arizona, have invented nevfad useful Improvements in Oil-Burners, of which the following iS a specification.

This' invention relates to oil burners.

The object of the present invention is to provide an improved form of oil burner adapted to be attached to the front or rear of' a tire box or furnace, and which is provided with a meansfm inducing a portion of the heated gas from within the fire box into the oil burner t-o'aid in the volatilization of the oil.; to provide means for adjusting the feed of the oil, and which has for its object the production of maximum elieieney in the 'vaporization and combustion of the oil.

The invention `consists of the parts and the combination and construction of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in Whieh- Figure 1 is a longitudinal vertical section through the burner. Fig. 2 is a plan view. Fig. 3 is a view'o't` the discharge end of the burner.

In the illustrated eiubodment of my invention, 2 represents a suitably shaped casing, having, preferably, a polygonal cross section, and which is formed at its forward end with a-reduccd portion forming a spraynozzle or tip il. which is adapted to project slightly into a fire box or furnace, the front of which is indicated at 4.

The casing 2 is provided with a valveehest 5, in which is Slidahly mounted a valve t3, which is oblong or rectangular in plan view, and effective to out oil' the flow of oil which is led into the valve chest 5 through i pipe 7, and. which passes, when the valve (l is open, through a port 8,havinga V-shape toward the front of the burner. The urpose ot' this particularly shaped port 8 is to enable thel operator to minultely control the volume ot oil as it passes t e slide-valve (3 and llows into the easing 2. By moving the valve (i outwardly, a very small V-'shaped opening is presented at.v the forward end of the valve so that :t very small quantity of oil can pass.

'l'he oil tlowing thiough the port 8 falls upon a shell or ltiingitudinal diaphragm 9, which 'projects ftu'oardly and. tern'iinates in Specification of Letters Patent.

a lip 10, from which the oil is discharged ontoV a trough 10 which forms the top wall indicated at `11 in the burner, in which the oil is atomized and mixed with a quantity of preheated air conducted into the interior of the casing 2 below the diaphragm 9 through opposite ports or passa eways 12 formed in the casing 2 at that e115 adjacent the valve chest A current of hot airis induced in'thcsc }.iassage\vays 12 when the burner is in opera# tion, the air being conducted to the passageways 12 through a horizontal, longitudinal suction-pipe 13, which projects toward the front 4 ot' the fire boxpor furnace and terminates, preferably. at a distance of about Aone and one-haltinches. more or less, from the front, leaving ainplc spaceefor air outside of the furnace front to flow into the suction pipe 13. The furnace front 4 is perforated. as at 14, forming an' opening considerably larger than the diameter of the suction pipe 13, and through which perfora'tion 14 a volume of the heated gas 0r air from the furnace may l'low into the Suction pipe when the burner is in operation.V`-

For the purpose ol assisting in atomizing the oil fed iulo the burner easing 2,' and discharging the atoinized'oil into the furnace, the steam pipe l5 is connected with the inside ot' the casing below the" oil passage,

head 1t, having an interior`clrimber 17,

wardlv and discharged through a reduced mouth 18 just inside of the reduced spraynezz/,le 3 of the burner.

ln operation, steam is admitted through thence discharged through the nozzle. lt-lmnd oil is admitted from the supply pipe 7 by shitting the controlling valve 6 so as to gradual! open the V-shaped port S when theI o il awuitted will descend, upon the shelf tially volatilizcd by the heat of the gas and furnace plate 4. 'lhisis a very important feature of the present invent-ion in thateertainA oils are vaporized more readily than \others, and such portions of the oil is flow along the shelt' 9 are quickly heated and thinned so that by the time the oil is discharged over tbe lip l0 it is readily atomized in the mixing chamber ll, and when to deliver a volume of steam intoa steam the pipo l5 into the steam chamber i7 and air induced in the passageways l2 from the. f

gf the Steam passage, and mixed in a space through which the steam is conducted for- Y 9 and th( 'ice onto the trough l0 to be pa'l'- I- drawn throu h the tip 3 the'blast.r of

I have found it Jexpedient, by lon'giexpei- 'i Y rience with oil burners,to\feed.the oil in a somewhat heated condition to..burners, and

the `temperature ofthe oil-thus fed in'A is nsuall between-100 and 125ci F.' While this beate oil. is readily atomized in the burner, this condition is facilitat/ed by the use of the .s

hot air induction pipe 13, which conveys the heated air beneath the diaphragm 9, greatly increasing the temperature of the oil before it is attunized.v The .heating eiect of.the air and gas in the induction pipe-1 3 is nicely controlled by means of an adjustable valve 20, rovded in the suction pipe, and which can e closed when necessary toA entirely cut.

Attention is particularly Vdirected to the peculiar `formation. of t he port 8 of the burner casing 2, by which means the controlV of the fuel from the burner is so perfect that a very small volume of oil may be ad- 'mitted .when desired, or the volume canbe quickly increased to the maximum capacity of the port 8 by moving oytwardly the slide valve 6, to which is connected an operating rod 6 projecting throu h the Valve chest. Having thus describe my inventioinwhat.
